LOCK.

SPECIFICATION forming part of Letters Patent No. 535,525, dated March 12, 1895.

Application filed March 6, 1894.. Serial No. 502,559. (No model.)

To @ZZ whom, it may concern:

Be it known that I, ROBERT R. BALL, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented a new and useful Locking Device, of which the following is a specification.

My object is to provide a locking device that can be substituted for ordinary door knobs, and which performs the functions'of a door knob and lock at will, and which can be used with any standard lock where a rectangular spindle is used to retract the latch bolt.

In the accompanying drawings, Figure l. is a sectional exhibit of the device divided on the line of, y, Fig. 6, end views of the nuts, A, A', and a mortise lock broken to show a hub, Q. Fig. 2. is a grooved spindle, H, separate from the knob, a rod, J, in the groove, and a sleeve nut, A, jacket, B, nut, O, yoke, D, and nut E, arranged consecutively as they are assembled upon the spindle, H. Fig. 3. is the knob, N', with the sleeve, T, mounted on the shank. Fig. 4. is a sectional exhibit of one knob divided on the line of, as, Fig. 6, and a rim lock; Fig. 5, a pair of knobs, the shank of the knob, N, divided in central section and the cam sleeve, T, divided in central section and mounted upon the shank of the knob, N; Fig. 6, a face View of the lock knob, N, showing the key hole, a; Fig. 7, the key.

Referring to the drawings, the broken lines represent a part lof a door stile. L, is an edge view of a common mortise latch broken to show the hub or follower, Q,witl1 the spindle passing through it. The knobs, N, N', are hollow. The axial hole, 6, in the sleeve nuts, A, A', is angular corresponding to the rectangular spindle, H, and their exterior surfaces are threaded. The roses, R, R', are of the ordinary style of construction.

Through the face of thelock-knob, N, is a key-hole, a', and the key when inserted connects with the spindle at l, to operate the latch-bolt. A tube, G, extends through the knob, N, and its shank, and is internally threaded at its point of contact with the rose plate'to accommodate the sleeve nut, A', and its exterior surface accurately fits the knobshank.

The spindle, H, is constructed with a cylindrical end, K, with a pin, l), through it, a

threaded end, I, to accommodate the nut, C, and is grooved longitudinally to accommodate an associate rod, J, which is preferably made of wire. The end, 2, of the rod, J, is threaded to enable the nut,E, to engageit and the end, 3, is hooked or bent so as to be at a right an-4 gle to the main length of the rod. In assemblage, the rod, J, is housed within the groove its end, 3, projecting at right angles to the spindle. This spindle, H, is capable ofa sliding movement when the parts are assembled and the cylindrical part, K, is flattened or grooved at, 1, so asto enable a key to engageit.

The washers, w, w', are pierced axially with a round hole, and accurately fit the interior of the tube, G, and in use are mounted upon the cylindrical part, K, of the spindle and serve to center it.

The spiral spring,f, encircles the cylindrical part, 7c, of the spindle and when the parts are all assembled, at one end engages the hooked end, 3, of the rod, J, pressing it against the washer, w, which in turn is in contact with and bears against the inner surface of the nut, A', and at the other end engages the pin, P, through the spindle.

In assembling the parts above described the sleeve nut, A', washer, w, and spring, f, are mounted upon the spindle, H, in the order mentioned. The pin is inserted and the washer, w', then mounted upon the spindle. The rod, J ,is now placed within the groove with its end, 3, projecting between the washer, w, and spring,f. As thus assembled the cylindrical end, K, of the spindle is introduced into the tube, G, and the threaded nut, A", engaged with the threaded end, of the tube, provided for it. The tube, G, is now placed into the knob, N, the tube extending the entire length ofthe knob and its shank, and fastened by machine screws passing through holes in the knob shankandtube,G,intothenut,A. The nut is thus fastened rigidly to the knob shank. The spindle is not rigidly fast tothe knob, N. The spring,f, having bearings as above described keeps the rectangular part in engagement with the square axial hole, 6, in the nut, A. When desired the angular part `of the spindle is withdrawn from its engagement with the angular hole, 6, permitting the knob, N, to freelyrevolve upon the cylindrical part, Y K, (shown in Figs. 1 and 5.)

I the spindle.

The hooked end, 3, has a bearing against the washer, QU, and in sequence with the rigidly fastened nut, A', and holds the knob, N, irrnlyin contact with the rose plate, R, when fastened at the end 2.

The knob, N', is designed to be aiiixed to the actuating spindle, H, upon the inside of the door and its shank is pierced with a longitudinal slot, S,'and' a round axial hole which is threaded at the part that comes in contact with the rose plate, to correspond and engage with the exterior screw threads ot' the sleeve nut, A.

The sleeve, T, mounted upon the shank of the knob, N', is constructed wit-h an incline or cam, t, also with the hole, F'-,'to provide for the passage of a set screw, F". This sleeve T, in operation has a bearing against either the rose plate, R' as shown in Fig. i,orfagainst a flange on the end of the shank of the knob, N',`as seen in Fig. 3.

The jacket, B, (Fig. 2) is constructed with an axial angular hole to fit the rectangular spindle upon which it `ismounted when in use. It is also fiattened upon two opposite sides to provide for the adjustment of the yoke, D, and\is pierced with a threaded hole, F, to engage a set-screw F. The sleeve nut, A, and jacket, B, are adjuncts to the spindle, H, and are adjustable to different thickness by sliding upon it. The nut C, run upon the threaded part, I, of the spindle adjusts both in place.

The fork yoke, D, is adapted to and applied to the rod, J, for the purpose of fastening it and preventing alongitudinal movement. In use, the fork, 2, 2, straddies the attencd sides of the jacket, B, and the square nut, C, the points touching the sleeve nut, A. A holeis punched through the end of the yoke through which the threaded end, 2, of the rod, J, projects, andthe nut, E, when run upon the rod, adjusts the yoke and keeps it in place.

Tightening the nut, E, draws the knob, N, by means ofthe coupling rod, J,- firmly against the rose plate, R', but the rectangular spindie, H, with the jacket, B, and nut, C, mounted upon it is permitted a reciprocating movement. The yoke, D,-`is provided with lugs, 3, 3, which in use clutch the square sides of the nut, E, by being squeezed upon it and act as a nut lock. In turn the forked yoke, D,locks the nut, C, by straddling it and thejacket, B.

To attach the knob, N, or the two knobs, N, and N', to doors, the spindle, H, with the coupling rod, J, housed in the groove is thrust through the hub of the lock after the manner of common handles. The sleeve nut, A, is placed upon the spindle so as to touch the rose plate, R'. The jacket, B, is then placed upon the spindlej ust touching the sleeve nut, A, and the nut, C, is run upon the spindle to hold both in place. The fork yoke, D, is then adjustediby the fork, 2', 2, straddling the {lattenedsides of the jacket', B, and justtouching the sleeve nut, A. The end of the rod,J, projects through the hole in the yoke and the nut, E, run upon the rod tightens the yoke against the sleeve nut, A, perfectly adjusting the knob, N, and holding it firmly to the door. The lugs, 3, 3, upon the yoke, D, are now squeezed down upon the nut, E, to lock it. The inside knob,N', is mounted upon the jacket, B, and is then screwed upon the sleevenut, A. When the shank touches the rose plate, R', the hole, F', in the cam sleeve, T, is on line with the threaded hole, F, in the jacket, B, and the set screw, F", through. the hole, F', and slot, S,is screwed'inplace. The set screw, F", as iinally adjusted projects through the slot, S, and engages the cam or incline, t, (as shown in Fig. 5.) This prevents the unscrewing of thek-nob, N', and makes a working connection between thermanipulating sleeve, T, and the rectangular spindle, H, by means of the jacket, B, whichas previously set-forth isan adjunct to the spindle. The spindle, H, iscontinuous, from thefknob,

N, through the hub, Q, of the latch bolt to' the. knob, N', and is not afixed to either knob, but is permitted a reciprocal movement in entirety. By turning the sleeve, T, to the right the incline, t, engages the set screw, F", and moves the spindle, H, so as to disengage the rectangular part from the square hole, 6, in the n ut, A', which is rigidly afiixed to the knob, N. The knob, N, is now free to revolve upon the cylindrical part, K, of the spindle, and-is useless for the purpose of retracting the latch bolt, m. The insertion of the key through the key hole, c', re-establishes the connection by the key engaging the spindle at, l. and the latch bolt can be retract-ed and the door opened. The reverse movement ofthe sleeve, T, releases the spindle from the pressure of the incline, t, and the tension of the spring,f, draws the spindle into the knob, N, causing the re-engagement of the spindleI with the knob, by means of the rectangular part and the angular hole, 6, (see Fig. 5) and the knobs can be used after the manner of handles in common use without the intervention of the key. Y

As illustrated in Fig.- 4, the manipulating nut, T', is threaded to correspond to the threaded end, l, of the spindle, H, and -is d-irectly run upon it. )Vhen the knob is mounted for service this nut has a bearing against the rim lock or rose plate, as the case may be. The forkI yoke,-D, is adjusted lo the rod, J, the fork, 2, 2, ineasy contact with.v the nut and is held and locked in place, after the manner heretofore setforth. The manipulating nut, T', is'heid firmly against the rim lock by the yoke, D, bearing directly againstit. The rod, J, having no longitudinal movement the nut, T', is confined in such manner as to prevent its running upon the threaded spindle, H, but the'spindle being free as described must move IOO IIO

longitudinally through the nut when the nutv is screwed either to the right or to the left. By this movement the rectangular part of the spindle, H, and the revoluble knob, N', are interlocked or disconnected. This arrangement of the device is particularly applicable to closets or where only one knob or a lock knob is required.

It will be observed that the means set forth for interlocking and disconnecting the revoluble knob and spindle enables lthe locking or unlocking the door from the inside independent of a key which is very desirable for inside doors.
